Application aleafnovember 25, 1911. serial No. 662,357.

To all whom 'it may concern:

Be it known that I, JOHN E. LANG, a citizen of the United States ofAmerica, residing at Washington, in the county of Washington and Stateof Pennsylvania,

1 yhave invented certainfnew and useful Imprqvements in Sealing Devicesfor Wrap- ,pers, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to a sealing device forwrappers, especiallydesigned for sealing the wrappers or inclosures of bread and otherperishable material.

The primary object of my invention is to provide a sealing device bywhich wrappers or inclosures can be expeditiously and economicallysealed upon bread and other` matter to insure cleanliness'andpalatableness of the contents of the wrapper or inclosure.

Another object of this invention is to provide a device that canv beadvantageously `used by the large producers of bread, cakes and suchmatter that can be wrapped in specially preparedv paper ory othermaterial to provide an air-tight inclosure.

' A further object of this invention is to v provide a sealing deviceembodying a hot table and a cooling table, bothy of which are strong anddurable, inexpensive to manufacture, and highly ethcient for thepurposes for which they are intended.

With the above and other objects in View, the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed. Y

' Reference will now be had tov the drawing,- wherein I 40 Figure 1 is aperspective view of the sealing device, and Fig. 2 is an enlarged crosssectional View of the same.

A sealing device in accordance with this invention comprises invertedU-shaped frames l, constituting supports. lThese frames are connected bylongitudinal` parallel bars 2 providing an oblong support for the maintable of the sealing device.

Suitably secured to thelongitudinal bars 2, at one end thereof, byrivets or other fastening means 3, is the bottom plate 4 of a heatingtable, said bottom plate having vertical oppositely disposed side walls5, with the ends of said walls, at one of the supports of the table,flared or bent outwardly, as at 6, whereby a wrapped loaf of bread orother material can be easily placed upon the table and moved thereon.

Secured to the bars 2, at the opposite end of the device, is a coolingtable 7 constructed similar to the heating table, said cooling tablehaving the end thereof confronting the end of the heating table flared,as at 8,

whereby wrapped loaves of' bread or other material can be readily movedfrom the heating table on to the' cooling table.

The heating and cooling tables are preferably made of copper or lightand durable metal, copper being used in connection with the heatingtable on account f its conductivity, the advantage of which willpresently appear.

The bars 2, beneath the heating table, are provided with hangers orstraps 9, said straps or hangers belng secured to the bars by screws 10or other/fastening means.

Located in the straps 9 is a gasburner,-

comprising a pipev 11 having the rear end thereof capped or plugged, asat 12. The pipe 11, at the opposite end, has a conventional form ofair'miXer 13 and said mixer isconnected to a gas supply pipe 14. Thepipe 11, intermediate the ends thereof, has an opening 15 and said pipe,adjacent to the walls 5 of the heating table, is provided with openings16. These openings cooperate with the opening 5A in providing an outletfor gas and when the gas is' ignited, the flame from the opening 15spreads against the bottom of the plate 4, while the fla-mes from the`openings 16 eX- tend upwardly alongthe outer sides of the wall 5 andthoroughly heat said walls, whereby the entire heating table willpresent a heating surface to the wrapper or inclosure of the materialthat is passed over said heating table.

As an instance of the material that can be i sealed in connection withthe device, the reference numeral 17 denotes a' wrapped loaf of bread.It is a well known fact that bread and other materials are wrapped andsealed in a specially prepared paper, for\ instance paraiin paper, andit is .the object of this invention to melt a portion of the paraffinupon a wrapper, whereby the folded become accidentally displaced. Inother words, the heating table has the same prinvlwrapped loaves ofbread can 115y ciplerinvolved as though an iron vwas employed for ironinthe wrap er lupon a loaf of bread; The heating table causes the wrapperto assume a definite shape, that completely incloses the loaf of breads.As the loaves of wrapped bre-ad are moved from the heating table on tothe 'cooling table, the wrap er has suiiicient time to become cooledbefbre being removed from the cooling table. It l is vapparent from theforegoing tha be expedi-4 tiously handled by the sealing device, andthatvva uniformity of packing -is obtained that could not be otherwiseaccomplished by manually wrapping and sealing loaves of bread orirregularly shaped bodies. A

It is thought that the operation and utility of the sealing device willbe apparent Vwithout further description,- and while in the drawingthere is illustrated a preferred embodiment of the'invention, it'is tobe understood that the structural elements thereof are susceptible tosuch changes as fall within the scope of the appended claims.

1. A sealing device for wrappers comprising supports, longitudinal barsconnecting said supports, a heating table located upon said bars at oneend thereof, a cooling table locatedv upon'said bars at the opposite endthereof and alining with and spaced from saidl heating table, each ofsaid tables of a width equal to the length of the article operated upon,and a burner located beneath said heating table and adapted to heat thebottom and side walls thereof.

, 2. A sealing device for wrappers embodying supports, longitudinalparallel bars carried thereby, a heating table secured to said bars andhaving side walls with the ends thereof flared at one end of saiddevice, a

coolin table arranged upon' said bars at the.

opposite end of said device andhaving the walls thereof flaredconfronting the end of .said heating table, straps carried. by said 3. Asealing device forl loavesfof bread embodying a heating table,`a coolingtable p alining therewith, said heating table-having one endthereofflared vwherebyfa wrapped' loaf of bread can easily enter" saidtable, each of'said tablesof a width' equal to the length of the articleoperated upon and said tables spaced from each other, and means arrangedtransversely of the bottom of said lheating table for heating the bottomand side walls of said t-able.

4. A sealing device for wrappers for loaves of bread, comprising aheating table y including a-bottom and a pair of side walls, said table'open at each end, a cooling table arranged in longitudinal alinementwith and spaced from said heating table including a bottomand a pair ofside walls and open at each end, supporting means for the outer lend ofsaidt-ables and supporting means forl the bottom of each kof saidtables.

5. A sealing device fol wrappers for loaves of bread, comprising aheating table v including a bottom and a pair of side walls, said tableopen at each end, a cooling table arranged in longitudinal alinementwith and spaced from said heating table includsov ing a bottom and apair of side walls and open at each end, supporting means for the outerend of said tables and supporting .means for the bottom of each of saidtables, each of said tables of a width slightly greaterthan the lengthof the loaf.V v

In testimony whereof I aix my signature in thepresence of two witnesses.
